Looking for Answers about Random House, Inc Black Diamond and Blake?

Black Diamond was the fastest, the best. After every race he'd stand with a wreath around his neck while cameras clicked and smiling people called him champ. But when he stumbles and hurts his leg, all that vanishes. Black Diamond's new home has high walls topped with razor wire, and the men who live there are called prisoners. Will anyone in this strange new place think he's the best, treat him like a champ?
